Anyone who has fat can have lipofilling breast augmentation. To choose between autologous fat breast augmentation or breast implants, it depends on two factors: one, the candidate’s personal wishes and preferences. Second, the candidate’s personal foundation. Autologous fat breast augmentation can achieve the effect of increasing 1-2 cup sizes through one-time filling, and its advantage is that the material is taken from the body, there is no exclusion, and it is safer. The postoperative effect also feels softer and more real. The procedure of breast augmentation with autologous fat is less traumatic and has a shorter recovery period. The disadvantage is that there is a possibility that multiple injections may be needed to achieve the desired results, but this is not absolute. Generally, after the fat is absorbed and activated and purified into pure fat particles, the fat is injected into the breasts, and the survival rate is also higher, so the vast majority of candidates can achieve satisfactory results through a single injection. Especially for those who have flat chest development but have certain breast tissue foundation; those who have sagging, flaring, different sizes between left and right, and need local shaping; and those who have atrophied and deformed chests due to childbirth and breastfeeding, they are very suitable for breast augmentation with autologous fat. The advantage of breast augmentation with implants is that it can increase several cup sizes at one time, but the disadvantage is that it will feel worse than breast augmentation with autologous fat, and the naturalness will be weaker. There are four types of incisions for breast augmentation, axillary incision, circumareolar nipple incision (Ω incision), areola incision and inframammary fold incision. Doctors usually choose the most suitable incision method according to the actual situation of the candidate. These incisions are more invasive than breast augmentation with autologous fat, and the postoperative recovery period is also longer. In addition, there are some complications, such as hardening contracture, implant margins, etc. The implant chosen by the surgeon and the surgeon’s surgical technique are related, and an experienced surgeon will have better results and can effectively avoid the appearance of postoperative complications.
